Airplay would work for the audio from my ipod which is what I'm doing now. But, what I really want to do is take my zone 2 outputs from my main AVR and send it to my dining room receiver. That way I can take whatever source I want be it my media server, Blu Ray player, TV, etc. and send it to the patio speakers. I have everything doubled up to the analog inputs so I know I can get all that through the zone 2 outputs. I just need some way to "beam" it across the house if you will.
